Green Computing Green Computing Saves Green Green Computing Saves Green The good news is, by As computers play an ever-larger role in our lives, energy demands, costs, and waste embracing simple, are escalating dramatically. Consider the following from the Climate Savers Computing everyday green Initiative: computing practices, you can improve • In a typical desktop computer, nearly half the power coming out of the wall is wasted energy management, and never reaches the processor, memory, disks, or other components. increase energy efficiency, reduce • The added heat from inefficient computers can increase the demand on air e-waste, and save conditioners and cooling systems, making your computing equipment even more money in the process! expensive to run. • Even though most of today’s desktop computers are capable of automatically transitioning to a sleep or hibernate state when inactive, about 90 percent of systems have this function disabled. • Some 25 percent of the electricity used to power home electronics—computers, DVD players, stereos, TVs—is consumed while the products are turned off. back | next
  4. 4. Green Computing Four Costly Computer Myths Four Costly Computer Myths 1 You should never turn off your computer. Your computer is designed to handle 40,000 on/off cycles. If you are an average user, that’s significantly more cycles than you will initiate in the computer’s five-to- seven-year-life. When you turn your computer off, you not only reduce energy use, you also lower heat stress and wear on the system. 2 Turning your computer off and then back on uses more energy than leaving it on. The surge of power used by a CPU to boot up is far less than the energy your computer uses when left on for more than three minutes. 3 Screen savers save energy. This is a common misconception. Screen savers were originally designed to help prolong the life of monochrome monitors. Those monitors are now technologically obsolete. Screen savers save energy only if they actually turn off the screen or, with laptops, turn off the backlight. 4 Network connections are lost when computers go into low-power/sleep mode. Newer computers are designed to sleep on networks without loss of data or connection. CPUs with Wake on LAN (WOL) technology can be left in sleep mode overnight to wake up and receive data packets sent to the unit. back | table of contents | next
  5. 5. Green Computing Did You Know… Did You Know… • An average desktop computer requires 85 watts just to idle, even with the monitor off. If that computer were in use or idling for only 40 hours a week instead of a full 168, over $40 in energy costs would be saved annually. • One computer left on 24 hours a day costs you between $115 and $160 in electricity costs annually while dumping 1,500 pounds of CO2 into the atmosphere. • A tree absorbs between 3 and 15 pounds of CO2 each year. That means up to 500 trees are needed to offset the annual emissions of one computer left on all the time! • If each household in a region the size of the metro Boston area turned off its computer for just one additional hour per day, it would save $3.2 million in electricity costs and prevent 19,000 tons of CO2 from heating the atmosphere. • Electricity production is the largest source of greenhouse gas emissions in the United States, ahead of transportation. back | table of contents | next

Look for non-chlorine bleached papers with 50 to 100 percent post-consumer waste. 15 Choose dark backgrounds for your screen display—bright-colored displays consumer more power. 19 Use double-sided printing functions. 16 Reduce the light level in your room when you are working on your computer. 20 E-mail communications as an alternative to paper memos and fax documents. back | table of contents | next
  9. 9. Green Computing How to Create a Green Machine How to Create a Green Machine Activating the power management features on your computer saves energy and money while helping the environment. Your computer’s SLEEP and HIBERNATE settings are two of the most effective ways for you to make your computer more environmentally friendly. You can activate these functions manually or through your operating system’s pre-set power management settings. Ideal for when you Sleep Mode are away from your Sleep or standby mode conserves energy by cutting off power to your display, hard drive, computer for frequent, and peripherals. After a pre-set period of inactivity, your computer switches to a low power short periods of time. state. When you move your mouse or press any computer key, you exit sleep mode and your computer takes you back to its previous operating state. Sleep mode is an especially effective way to conserve battery power in a laptop computer. However, if your computer loses power for any reason while in sleep mode, you may lose unsaved work. Ideal for when you Hibernate Mode are away from your Hibernate mode saves energy and protects your work by copying system data to a computer for extended reserved area on your hard drive and then completely turning off your computer. It also periods of time. reduces wear and tear on your components. When you turn power back on, your files and your documents appear on your desktop just as you left them. Be sure to set your system to automatically go into hibernate mode any time your battery power reaches a critically low level. back | table of contents | next

  11. 11. Green Computing Do You Believe in Vampires? Do You Believe in Vampires? You’d better. In fact, there are probably several vampires in your home right now, sucking power from your electric outlets and money from your wallet. Anything that uses When your computer, plasma TV, or stereo is off, you probably think it is using as little power as possible. Fact is, a remote continues these devices have high standby power use. What’s more, all of the peripherals connected to your computer— to consume power printer, monitor, USB hub, scanner, DSL/cable modem, etc.—continue to consume “idle current” as well. even when it’s turned off—for example, when There may be as many as 20 devices drawing standby power in your home. These include any device with a remote a TV is “off,” it’s really control and external power supply (or adapter), permanently illuminated digital displays and LEDs, and many new partially “on” so that larger appliances, such as air conditioners and refrigerators. the picture comes on quickly when you hot According to the Department of Energy, “vampire energy loss” represents between 5 and 8 percent of a single- the remote. This is family home’s total electricity use per year. On average, that equals one month’s electricity bill. Taken across the called “vampire energy United States, it adds up to at least 68 billion kilowatt-hours of electricity annually—that’s the equivalent output of use” or “phantom 37 typical electricity-generating power plants, costing consumers more than $7 billion. The result of all this wasted energy use.” energy? More than 97 billion pounds of carbon dioxide seeping into the atmosphere each year. On a global scale, standby energy accounts for 1 percent of the world’s carbon emissions, according to Alan Meier of the Lawrence Berkeley National Laboratory in California. back | table of contents | next 11
  12. 12. Green Computing A Vampire’s Worst Nightmare: Surge Protection with Master Control A Vampire’s Worst Nightmare: Surge Protection with Master Control So how do you combat those vampire energy loads? Fortunately, when it comes to your computer and electronics, there’s an easy solution: a surge protector with a master control outlet. Simply plug your computer into the master outlet and your peripherals into the controlled outlets. The master outlet senses when your computer powers down or goes into sleep mode and automatically shuts down the controlled outlets. Your peripherals no longer suck up energy when they are in standby mode— and vampire loads no longer take a bite out of your monthly budget. back | table of contents | next 1
  13. 13. Green Computing Recycling E-Waste Recycling E-Waste A recent study by the EPA shows that electronics make up approximately 1 percent of the municipal solid waste stream. Research completed in Europe shows that electronics waste is growing at three times the rate of other municipal waste. Clearly, an essential part of green computing includes proper disposal of components that you no longer use. How Much E-Waste Is Out There? • In a 2006 report, the International Association of Electronics Recyclers projects that with the current growth and obsolescence rates of the various categories of consumer electronics, approximately 3 billion units will be scrapped during the rest of this decade, or an average of 400 million units a year. • Gartner has estimated that 133,000 personal computers are discarded by U.S. homes and businesses each day. • Each year 130 million cell phones are retired. • According to the EPA, we generated 2.6 million tons of e-waste in the U.S. in 2005, or 1.4 percent of total discards. Of this amount only 12.6% was recycled. • About 68 percent of consumers stockpile used or unwanted computer equipment in their homes. back | table of contents | next 1

  16. 16. Green Computing Key Takeaways Key Takeaways • About 25 percent of the electricity used to power home electronics is consumed when the devices are turned off. • It takes less energy to boot up a computer than it does to leave it running for more than 3 minutes. • Plug functionally related electronics into a surge protector (or UPS) that features a master outlet/controlled outlet technology to avoid vampire energy use. Example: Plug a computer into the master outlet and the peripherals (printer, speakers, etc.) into the controlled outlets. When the computer powers down, the master outlet automatically shuts off power to the peripherals. back | table of contents | next 1
